432597 ÷ 18 
Our goal is to divide 432597 by 18.

Going ahead to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 18

Moving on to step 2:
18 can be fit into 43 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 36 from 43, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 18

Moving on to step 3:
When dividing 72 by 18, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 72 away from 72, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 18

On to step 4:
If we divide 5 by 18, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 18

Step 5:
18 can be fit into 59 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 2403.0
The remainder is 5 after subtracting 54 from 59.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 18

On to step 6:
18 can be fit into 57 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 24033.0
If we subtract 54 from 57, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 24033.1
If we take 18 away from 30, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 24033.16
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 24033.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 24033.166, with a leftover of 0.0012.
